Answer:
51
Step-by-step explanation:
The mean is obtained by adding up the values in the data set and then divide by the number of values that you added:

Given our mean as 11.5 and n=4:

#Knowing our sum as 65, we can obtain x by subtracting sum of known values from 65:

Hence, the value of x is 51
The meal cost spent by Jack at the restaurant if he spent $15 including tip and bill is $11.79.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the meal cost, hence:
Total cost = x + 0.2x + 0.0725x
15 = 1.2725x
x = 11.79
The meal cost spent by Jack at the restaurant if he spent $15 including tip and bill is $11.79.

Answer:
f(5) = 26.672 which is option D
Step-by-step explanation:
From question, f(1) = 2 and f'(x)=√(x^3 + 6)
f(5) = f(1) + (5,1)∫ f'(x) dx
Integrating using the boundary 5 and 1;
f(5) = 2 + (5,1)∫√(x^3 + 6) dx
f(5) = 2 + 24.672
So f(5) = 26.672
Answer:
9 years
the tree doubles in height
we can make a model
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024
Let's say 1024 is the maximum height
half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year
